Research Progress in Selective Laser Melting of AluminumMatrix Composites

Aluminium matrix composites are an important lightweight material, and their corrosion behaviour in service environment is closely related to the safe operation of equipment. The selective laser melting (SLM) technology provides a new technological pathway for near-net-shaping and rapid manufacturing of the aluminium matrix composite parts with complex structures. In this study, the preparation principle of SLM technology, the research progress in the mechanical and corrosion resistance properties of SLM aluminium matrix composites are reviewed, and the future research direction of the SLM aluminium matrix composites is put forward.
